Monster DR and weaknesses

Monsters may be resistant to or fully protected from some forms of attack and vulnerable to others.

For reference, "normal" damage is shown with red numbers. Resistances (via DR) are indicated by yellow damage numbers: this means some of your damage is being reduced and it might be possible for you to overcome this by changing weapon type. To see what damage type you need to use, check the Combat Log. Full protection is indicated by white zero damage numbers. Some forms of damage are particularly effective against a monster and this is indicated by purple damage numbers. Green damage numbers indicate that the monster is actually healed by that type of damage; you see this occasionally with fire elementals being attacked by fire, for example.

DR Type:

"or" means one, or the other, of the DR overcoming types listed, such as silver or good to overcome devils.

"+" means that both (or all) listed damage types must be on a weapon to "break" the DR of the monster in question.

Alignment is listed here so that you can tell which alignment-based weapon enchantments will add extra damage; alignment-based damage is not required to break DR unless it is mentioned in the "DR" column.
